You can buy bi-xenon retrofit kits with shrouds. I think the OP custom made his shrouds because the projectors he used didn't come with them.
Current retrofit kits will come with projectors, shrouds, halos(if you want them), bulbs, ballasts, and all mounting hardware...everything you need.
Something like this is what you want. No "cup" needed
During installation.
Installed.
